Vehicle Control Device Suppressing Excessive Passing via Feature Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automated driving systems, frequent lane changes and excessive passing control occur when a host vehicle passes another vehicle, which can lead to unnecessary operations and safety concerns.
Innovation Solution
A vehicle control device and method that recognizes the surrounding environment, performs passing control based on speed and steering, and implements suppression control to prevent excessive passing by matching feature information of vehicles and adjusting speed and distance thresholds, thereby reducing unnecessary lane changes and improving safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If passing control is performed based on speed relationship with preceding vehicle, then passing capability is improved, but excessive passing control and frequent lane changes occur
Solution Approach 1:
The system stores feature information of passed vehicles in advance in a storage unit. When a vehicle matching the stored feature information is detected, the system retrieves the stored information and performs suppression control, preventing the need for real-time decision-making and reducing excessive passing control.
Solution Approach 2:
The system establishes a feedback loop where passing control actions are recorded and stored as feature information. This feedback mechanism allows the system to learn from past passing behaviors and adjust future control decisions, suppressing excessive passing control while maintaining necessary passing capability.
2Reliability
If feature information matching is performed to suppress passing control, then excessive passing is reduced, but device complexity increases
Solution Approach 1:
The system creates simplified copies of vehicle feature information (such as vehicle identification characteristics) and stores them in a database. Instead of complex real-time analysis, the system compares current vehicle features against stored copies, reducing computational complexity while maintaining reliable suppression control.
3Speed
If speed threshold is lowered to enable passing control, then passing responsiveness is improved, but unnecessary lane changes increase
Solution Approach 1:
The system pre-stores feature information of vehicles that should not be passed. Even when speed thresholds indicate passing is appropriate, the system checks against stored feature information first, preventing unnecessary lane changes while maintaining responsive passing control for legitimate scenarios.
Solution Approach 2:
The system dynamically adjusts passing control decisions by combining speed threshold evaluation with feature information matching. The control parameters are not fixed but adapt based on both speed conditions and vehicle identification, allowing responsive passing when appropriate while suppressing unnecessary lane changes.

AI summary
A vehicle control device of an embodiment includes a recognizer configured to recognize a surrounding environment of a host vehicle and a driving controller configured to perform driving control by controlling one or both of a speed and steering of the host vehicle on the basis of a recognition result of the recognizer. In a case where a speed relationship between the host vehicle and a forward vehicle traveling in front of the host vehicle satisfies predetermined conditions, the driving controller is configured to perform passing control for passing the forward vehicle, and holds feature information of the forward vehicle under predetermined conditions.
